load property
Fires when the chart is finished loading. Since v4.2.2, it also waits
for images to be loaded, for example from point markers. One
parameter, event
, is passed to the function, containing common
event information.
There is also a second parameter to the chart constructor where a callback function can be passed to be executed on chart.load.
